Assessing the Impact of COVID-19 on Facial Aesthetic Surgery Search Interest.

ABSTRACT: The global COVID-19 pandemic reshaped many components of modern health care practice. Before the pandemic, research was beginning to demonstrate the impact of self-facing cameras, selfie images, and webcams on patient interest in head and neck (H&N) aesthetic surgery. We sought to determine temporal changes in patient interest in aesthetic surgery of the H&N as compared with the rest of the body because of COVID-19, and the subsequent surge in Web-conferencing and telecommunication. The 2020 Plastic Surgery Trends Report produced by the American Society of Plastic Surgeons was used to identify the 5 most common aesthetic surgical procedures performed on the H&N and the rest of the body for 2019: blepharoplasty, face lift, rhinoplasty, neck lift, cheek implant, and breast lift, liposuction, tummy tuck, breast augmentation, and breast reduction, respectively. Google Trends filters, which provide relative search interest for greater than 85% of Internet searches, were applied to gauge interest from January 2019 to April 2022. Relative search interest and mean interest were plotted as a function of time for each term. Our findings demonstrate a sharp decline in online aesthetic surgery interest in March 2020, coinciding with the beginning of the COVID-19 pandemic for both the H&N and the rest of the body. Search interest increased shortly after March 2020 and reached values greater than those of the prepandemic year (2019) in 2021 for rest of the body procedures. After March 2020, there was a brief, sharp increase in search interest for rhinoplasty, neck lift, and facelift, whereas patient interest in blepharoplasty increased more gradually. There was no increase in search interest for H&N procedures as a result of COVID-19 when using the mean values of the included procedures, although current interest has returned to prepandemic levels. The COVID-19 pandemic caused a disruption of normal trends in aesthetic surgery interest, with a sharp decline in search interest in March 2020. Afterward, there was a sharp increase in rhinoplasty, face lift, neck lift, and blepharoplasty interest. Patient interest in blepharoplasty and neck lift has remained elevated compared with 2019. Interest in rest of the body procedures has returned to and even surpassed prepandemic levels.

Topical application of cannabinoid-ligands ameliorates experimental dry-eye disease.

PURPOSE: Dry eye disease (DED) is a multifactorial disease, with limitations regarding efficacy and tolerability of applied substances. Among several candidates, the endocannabinoid system with its receptors (CB1R and CB2R) were reported to modulate inflammation, wound healing and pain, which are also core DED pathomechanisms. This study is to investigate the therapeutic responses of Δ-9 tetrahydrocannabinol (a non-selective agonist) and two selective antagonists, SR141716A (CB1R antagonist) and SR144528 (CB2R antagonist), as a topical application using a DED mouse model. METHOD: Experimental DED was induced in naïve C57BL/6 mice. Expression of CBR at the ocular surface of naïve and DED mice was determined by qPCR and in-situ hybridization. Either THC or CBR antagonists were compounded in an aqueous solution and dosed during the induction of DED. Tear production, cornea sensitivity, and cornea fluorescence staining were tested. At the end of each experiment, corneas were stained with ß3-tubulin for analysis of corneal nerve morphology. Conjunctiva was analyzed for CD4+ and CD8+ infiltration. RESULTS: CB1R and CB2R are present at the ocular surface, and desiccating stress increased CBR expressions (p < 0.05). After 10 days of DED induction, treated groups demonstrated a reduced CBR expression in the cornea, which was concurrent with improvements in the DED phenotype including fluorescence staining & inflammation. Applying THC protected corneal nerve morphology, thus maintained corneal sensitivity and reduced CD4+ T-cell infiltration. The CB1R antagonist maintained cornea sensitivity without changing nerve morphology. CONCLUSIONS: Endocannabinoid receptor modulation presents a potential multi-functional therapeutic approach for DED.

Readability and Understandability Analysis of Online Materials Related to Abdominal Aortic Aneurysm Repair.

BACKGROUND: Patients commonly use online materials as a source of health information. Since poor health literacy has been shown to correlate with negative outcomes, it is recommended that patient-directed materials be written at a sixth-grade reading level. This study evaluates the readability and understandability of commonly accessed online materials pertaining to both endovascular and open repair of abdominal aortic aneurysm. METHODS: Searches for "endovascular repair abdominal aortic aneurysm" and "open repair abdominal aortic aneurysm" were performed on both Google and Bing, and the top 10 websites from each search engine were identified. Relevant websites (total N = 28, endovascular n = 15, open n = 15, and 2 redundant sites) with patient-directed content were analyzed. Readability was assessed using 9 established methods, and understandability was assessed using the Patient Education Materials Assessment Tool scoring system. RESULTS: The average reading grade level for all sites was 12.8. Endovascular sites averaged a reading grade level of 13.6 with a range from 11.5 to 15.6. Open-repair websites had a grade-level average of 12.1 with a range from 9.9 to 14.1. Readability was found to be inversely related to understandability, with a Pearson correlation coefficient of -0.551 (P = .003). No website was written at or below the recommended sixth-grade reading level. CONCLUSIONS: Patient-directed online health information pertaining to open and endovascular repair of abdominal aortic aneurysm exceeds the recommended sixth-grade reading level. Increasing complexity of health literature correlates with poor understandability. Modifications such as shorter sentences, fewer words with more than 6 letters, and increasing usage of clear visual aids can increase readability and understandability.

The Current State of Surgical Ergonomics Education in U.S. Surgical Training: A Survey Study.

OBJECTIVE: The aim of this study was to characterize the current state of surgical ergonomics education in the United States. BACKGROUND: The burden of work-related musculoskeletal disorders (MSDs) in surgeons is high and no overarching strategy for redress exists. Twelve distinct specialties describe an unmet need for surgical ergonomics education (SEE). This study aimed to define the current state of SEE in U.S. surgical training programs. METHODS: We performed a descriptive analysis of a 20-item questionnaire of ACGME-certified program directors from 14 surgical and interventional medical specialties. Formal SEE was defined as any organized education module that reviewed the occupation-specific burden of common work-related MSDs and described a framework for prevention via occupation-specific applied ergonomics. Program directors were queried regarding SEE provision, characteristics, and perceived trainee attitude toward the education. RESULTS: Questionnaires were received from 130 of 441 (29.5%) program directors. Two (1.5%) provided formal SEE and 33 (25.4%) provided informal SEE, which consisted of unstructured intraoperative directives and isolated lectures. Two programs previously provided SEE but discontinued the effort due to lack of an evidence-based framework and instructors. Trainees appeared to think that learning surgical ergonomics skills was a worthwhile time investment in 100% and 76.7% of current formal and informal SEE, respectively. CONCLUSION: SEE is rarely provided in any capacity (25.4%), let alone in a consistent or evaluable fashion (1.5%). Impediments to sustainable SEE include lack of an evidence-based framework for education and instructors. An evidence-based, reproducible, and accreditation council-compliant SEE module would be a valuable resource for the surgical and interventional medical communities.

Technological Advances in Lymphatic Surgery: Bringing to Light the Invisible.

Lymphatic surgery has become an integral and flourishing component of the field of plastic surgery. The diversity of ongoing technological innovations in perioperative imaging, including intraoperative dyes and cameras, allows plastic surgeons to work at the supermicrosurgical level. This study aims to highlight innovations that have shaped and will continue to revolutionize the perioperative management of the lymphatic surgery patient in the future. As additional advances emerge, we need a systematic and objective way to evaluate the efficacy and clinical integration readiness of such technologies. Undoubtedly, these technologies will help lymphatic surgery trend toward increasing objectivity, which will be critical for continued evolution and advancement.

Utility of a Novel Three-Dimensional and Dynamic (3DD) Cell Culture System for PK/PD Studies: Evaluation of a Triple Combination Therapy at Overcoming Anti-HER2 Treatment Resistance in Breast Cancer.

Background: Emergence of Human epidermal growth factor receptor 2 (HER2) therapy resistance in HER2-positive (HER2+) breast cancer (BC) poses a major clinical challenge. Mechanisms of resistance include the over-activation of the PI3K/mTOR and Src pathways. This work aims to investigate a novel combination therapy that employs paclitaxel (PAC), a mitotic inhibitor, with everolimus (EVE), an mTOR inhibitor, and dasatinib (DAS), an Src kinase inhibitor, as a modality to overcome resistance. Methods: Static (two dimensional, 2D) and three-dimensional dynamic (3DD) cell culture studies were conducted using JIMT-1 cells, a HER2+ BC cell line refractory to HER2 therapies. Cell viability and caspase-3 expression were examined after JIMT-1 cell exposure to agents as monotherapy or in combination using a 2D setting. A pharmacokinetic/pharmacodynamic (PK/PD) combination study with PAC+DAS+EVE was conducted over 3 weeks in a 3DD setting. PAC was administered into the system via a 3 h infusion followed by the addition of a continuous infusion of EVE+DAS 24 h post-PAC dosing. Cell counts and caspase-3 expression were quantified every 2 days. A semi-mechanistic PK/PD model was developed using the 2D data and scaled up to capture the 3DD data. The final model integrated active caspase-3 as a biomarker to bridge between drug exposures and cancer cell dynamics. Model fittings were performed using Monolix software. Results: The triple combination significantly induced caspase-3 activity in the 2D cell culture setting. In the 3DD cell culture setting, sequential dosing of PAC then EVE+DAS showed a 5-fold increase in caspase-3 activity and 8.5-fold decrease in the total cell number compared to the control. The semi-mechanistic PK/PD models fit the data well, capturing the time-course profiles of drug concentrations, caspase-3 expression, and cell counts in the 2D and 3DD settings. Conclusion: A novel, sequential triple combination therapeutic regimen was successfully evaluated in both 2D and 3DD in vitro cell culture systems. The efficacy of this combination at inhibiting the cellular proliferation and re-growth of HER2/mTOR resistant cell line, JIMT-1, is demonstrated. A biomarker-linked PK/PD model successfully captured all time-course data. The latter can be used as a modeling platform for a direct translation from 3DD in vitro settings to the clinic.

Racial disparities in postmastectomy breast reconstruction: National trends in utilization from 2005 to 2014.

BACKGROUND: Evidence of racial disparities in the receipt of postmastectomy breast reconstruction is well documented. The objective of this study was to describe trends in racial disparities overall and by reconstructive technique. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was used to identify women who underwent mastectomy and/or breast reconstruction from 2005 to 2014. Patient demographics were recorded, and cases were grouped by reconstructive status and technique. Trends were assessed with the Cochran-Armitage test and the index of disparity. RESULTS: Over the study period, 92,960 postmastectomy patients were identified (77,049 white women, 10,396 black women, 4939 Asian women, and 576 Native American women), of whom 46,931 underwent reconstruction. Of these, 7692 women underwent autologous reconstructions (3913 free flaps and 3696 pedicled flaps). From 2005 to 2014, receipt of breast reconstruction by postmastectomy patients rose from 33.2% to 60.0%, receipt of autologous reconstruction by patients who underwent breast reconstruction fell from 30.4% to 15.9%, and receipt of free-flap reconstruction by patients who underwent autologous reconstruction rose from 15.0% to 70.8%. These trends were significant in all racial subgroups (P < .001), except for Native Americans (P = .269). The index of disparity decreased from 51.4% to 22.6% for overall receipt of breast reconstruction, decreased from 10.7% to 7.0% for tissue expander and implant-based reconstruction, increased from 18.0% to 27.3% for autologous reconstruction, and decreased from 66.7% to 4.3% for free-flap reconstruction. CONCLUSIONS: The use of postmastectomy breast reconstruction is steadily rising in the United States. Racial disparities persist, but progress has been made. Further efforts are needed to reduce racial disparities. Cancer 2018;124:2774-2784. © 2018 American Cancer Society.

Prevalence of Work-Related Musculoskeletal Disorders Among Surgeons and Interventionalists: A Systematic Review and Meta-analysis.

Importance: Physicians in procedural specialties are at high risk for work-related musculoskeletal disorders (MSDs). This has been called "an impending epidemic" in the context of the looming workforce shortage; however, prevalence estimates vary by study. Objectives: To estimate the prevalence of work-related MSDs among at-risk physicians and to evaluate the scope of preventive efforts. Data Sources and Study Selection: Systematic search in MEDLINE (Ovid), Embase (Elsevier), Web of Science, PubMed (National Center for Biotechnology Information), and 2 clinical trial registries, without language restriction, for studies reporting on the prevalence and prevention of work-related MSDs among at-risk physicians published until December 2016. The Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines for meta-analyses and systematic reviews of observational studies were used. At-risk physicians were defined as surgeons and medical interventionalists. Studies reporting on specific disorders or pain assessed with validated instruments were included. Data Extraction and Synthesis: Study characteristics; disease prevalence for the neck, shoulder, back, and upper extremity; and measures of resulting disability were recorded. Study estimates were pooled using random-effects meta-analytic models. Main Outcomes and Measures: Career prevalence of injuries and 12-month prevalence of pain. Results: Among 21 articles (5828 physicians [mean age, 46.0 years; 78.5% male; 12.8 years in practice; 14.4 hours performing procedures per week]) included in this systematic review and meta-analysis, pooled crude prevalence estimates of the most common work-related MSDs were degenerative cervical spine disease in 17% (457 of 2406 physicians) (95% CI, 12%-25%), rotator cuff pathology in 18% (300 of 1513 physicians) (95% CI, 13%-25%), degenerative lumbar spine disease in 19% (544 of 2449 physicians) (95% CI, 5%-16%), and carpal tunnel syndrome in 9% (256 of 2449 physicians) (95% CI, 5%-16%). From 1997 to 2015, the prevalence of degenerative cervical spine disease and degenerative lumbar spine disease increased by 18.3% and 27%, respectively. Pooled prevalence estimates for pain ranged from 35% to 60% and differed by assessment instrument. Of those with a work-related MSD, 12% (277 of 2319 physicians) (95% CI, 7%-18%) required a leave of absence, practice restriction or modification, or early retirement. Heterogeneity was considerable for all crude analyses (mean I2 = 93.5%) but was lower for sensitivity analyses (mean I2 = 72.3%). Interventions focused on products and behaviors. Twelve at-risk specialties described a gross lack of awareness and an unmet need for ergonomics education. Conclusions and Relevance: Prevalence estimates of work-related MSDs among at-risk physicians appear to be high. Further research is needed to develop and validate an evidence-based applied ergonomics program aimed at preventing these disorders in this population.

Work-Related Musculoskeletal Disorders among Plastic Surgeons: A Systematic Review.

BACKGROUND: To date, no review has been conducted on the growing body of literature describing various work-related musculoskeletal disorders (MSDs), ergonomic hazards, and potential interventions relevant to plastic surgeons. This systematic review sought to (1) define the scope of coverage of this important issue in the peer-reviewed literature; (2) critically assess the evidence; and (3) provide recommendations for future directions. METHODS: We conducted a literature search of MEDLINE, Embase, Web of Science, and PubMed from the inception of each database until 2016. All articles reporting on work-related MSDs or ergonomics among plastic surgeons were reviewed, summarized, and assessed for trends. RESULTS: Sixteen articles met our inclusion criteria including five expert opinions, four cross-sectional studies and case reports/series, one review, and six experimental studies. Four articles presented evidence on disease burden. The most commonly described work-related MSD was cervical spine disease, for which one study reported a career prevalence of 24.7% (point prevalence in the general population: 0.1-0.4%); three studies reported 64 cases of surgeon work-related MSD resulting in surgical intervention, decreased productivity, or involuntary early retirement. Eight studies described interventions, most of which aimed to improve the ergonomics of microsurgery. CONCLUSION: This review found low-level evidence of plastic surgeons' vulnerability to a work-related MSD at times severe enough to end careers. Further investigation is needed to clearly define this important problem in plastic surgery. Specifically, future directions should include more methodologically rigorous epidemiologic studies evaluating disease burden.
